Abstract: Disclosed are a method and a device for transmitting/receiving a reference signal by a terminal in a wireless communication system. According to the present disclosure, the terminal receives control information from a base station and receives the reference signal based on the control information. The reference signal is transmitted on a specific antenna port and is positioned in the same symbol, on a time axis, and in the same subcarrier, on a frequency axis, as a different reference signal transmitted on at least one other antenna port. A method and a device may be provided, in which an Orthogonal Cover Code (OCC) is applied to the specific antenna port and at least one other antenna port and multiplexed through a Code Division Multiplexing (CDM) scheme and the OCC or a value acquired by shifting the OCC is applied to the subcarrier according to the index of the subcarrier.

Abstract: Disclosed herein are a method and apparatus for transmitting/receiving random access signals. A user equipment (UE) transmits a random access preamble of a random access procedure through a random access channel (RACH) resource associated with a synchronization signal (SS) block. A base station (BS) receiving the random access preamble from a UE can transmit CSI-RSs to the UE. The BS may inform the UE that there will be CSI-RS transmission to the UE, during the random access procedure.

Abstract: A base station transmits low-density configuration information and high-density configuration information on a channel state information-reference signal (CSI-RS) of a beam. A user equipment performs beam measurement, using a CSI-RS received on the basis of the low-density configuration information (hereinafter, a low-density CSI-RS), and performs time tracking, using a CSI-RS received on the basis of the high-density configuration information (hereinafter, a high-density CSI-RS). At least in a frequency domain, the high-density CSI-RS is configured to have a higher density than that of the low-density CSI-RS.

Abstract: A method and apparatus for performing a random access procedure in a wireless communication system is provided. A user equipment (UE) triggers the random access procedure. When a physical random access channel (PRACH) resource is not in an active uplink (UL) bandwidth part (BWP), the UE switches the active UL BWP to an initial UL BWP, and switches an active DL BWP to an initial DL BWP. When the PRACH resource is in the active UL BWP, the UE switches the active DL BWP to a DL BWP which is paired with the active UL BWP.
